Coaltoliquids (CTL): The conversion of coal to liquid fuels and/or chemicals. Coprocessing (of coal): The simultaneous conversion of coal and waste carbonaceous feedstocks such as petroleumbased residual oil or tar, plastics, or rubbers via oncethrough direct liquefaction into liquid, solid, and gaseous hydrocarbonaceous materials intended primarily for use as fuel
The process of converting solid coal into liquid fuel. ex:wildly used by the german military relatively expensive ctl has the potential to eliminate us dependence on foreign oil but the total greenhouse gas emissions are more than twice those from conventionally produced oil; 1000 times more energy in the worlds coal reserves than petroleum

Gasification. Gasification technology is effective for conversion of carbonaceous fuels into combustible gas, which can be used for various applications including generation of heat, power or combined heat and power, or being further processed for synthesis of liquid fuel and other chemicals.
process, involves the gasification of coal, and its subsequent conversion into liquid hydrocarbons. The gasification step yields carbon monoxide and hydrogen, together with CO 2 and methane. When the carbon monoxide and hydrogen mixture is passed over a catalyst — usually a form of iron or cobalt — it is converted into liquid hydrocarbons.
A process called biosolubilization utilizes the role of microorganisms to convert solid coal into liquid fuel/chemical compounds while still producing environmentally friendly by products. Furthermore, lignite contains simple aromatic compounds which is a favourable condition to optimize the process.
Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum. Therefore, conversion of coal into liquid fuels involves the addition of hydrogen.
CoaltoLiquids. CoaltoLiquids (CTL) is a process of converting coal to fuels such as diesel or gas. For diesel, the process involves first building a plant to convert coal to gas and then another plant to covert the gas to a liquid. The resultant liquid fuel is known as synthetic fuel or synfuel. Synfuels are used as an alternative to oil ...

Summary: Researchers developed an efficient process that can convert carbon dioxide into formate, a nonflammable liquid or solid material that can be used like hydrogen or methanol to power a fuel ...
Coal to Liquids (CTL) as well as Integrated Gasification Combined Cycle (IGCC) plants take advantage from the conversion of a cheap, fossil fuel like coal into a clean synthetic gas, mainly composed of hydrogen, carbon monoxide, carbon dioxide and other minor species, either to produce Liquid Fuels or Electricity as output.
The process of coal liquefaction creates synthetic liquid fuels from solid as substitutes for various petroleum products. There are two types of liquefaction direct and indirect . Direct liquefaction converts solid coal directly into liquid form with no intermediate step, which results in only the partial dismantling of the coal structure.
The key to the catalytic process is the construction of a highly efficient tandem catalyst PtMo 2 C/C + Ru/C, which can directly convert CO and H 2 O in aqueous phase to liquid hydrocarbons with ...

Unlike coalfired power plants, where coal's combustion emits pollutants, CTL fuels are as clean or cleaner at their end use as today's liquid fuels. But the process by which the fuels are made can be very carbonintensive — in fact, more so than any other fuel — and that has many people concerned.
This process is termed coaltoliquid (CTL) and is a reasonably mature technology. The process typically uses the technique of heating under pressure (up to 470°C, 200 bar) and hydrogenation where hydrogen is added to a coalwater slurry.
The FischerTropsch process (or FischerTropsch Synthesis) is a set of chemical reactions that convert a mixture of carbon monoxide and hydrogen into liquid process, a key component of gas to liquids technology, produces a petroleum substitute, typically from coal, natural gas, or biomass for use as synthetic lubrication oil and as synthetic fuel.

The FischerTropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid reactions occur in the presence of metal catalysts, typically at temperatures of 150300 °C (302572 °F) and pressures of one to several tens of FischerTropsch process is an important reaction ...
These temperatures optimize the production of coal tars richer in lighter hydrocarbons than normal coal tar. The coal tar is then processed into fuels. All these liquid fuel production methods release carbon dioxide in the conversion process, far more than is released in the extraction and refinement of liquid fuels from petroleum.
Coal liquefaction is the process of converting solid coal into liquid fuel. This process has been developed as a means to utilize coal resources that are otherwise difficult to access and transport. The resulting liquid fuel, called synthetic crude oil, can be refined into a variety of fuels, including diesel, gasoline, and aviation fuel.
Gasification While the goal of combustion is to produce the maximum amount of heat possible by oxidizing all the combustible material, the goal of gasification is to convert most of the combustible solids into combustible gases such as carbon monoxide, hydrogen, and methane. Gasification reactions
Indirect liquefaction processes require first gasifying the solid feedstocks into a syngas. Therefore, while direct coal liquefaction (DCL) takes coal directly into a liquid phase, indirect coal liquefaction (ICL) consists of two major steps: (a) gasification to produce a synthesis gas (syngas); and (b) conversion of the carbon monoxide (CO) and hydrogen (H 2) in the syngas to a range of ...
